Hugo Henneberg was a leading Austrian pictorial photographer who became well known in the United States. With Heinrich Kuehn and Hans Watzek, the only other Austrians to be represented in Camera Work, he formed a union they called Das Kleeblatt (the Trifolium). The three made trips to other countries together, exhibited as a group, and earned a reputation for their large-scale gum-bichromate prints, some as big as 3 by 4 feet. In Villa Falconieri, Henneberg used an exaggerated vertical format and an expansive foreground to create a dramatic pictorial effect. Like much of his other work, this photograph shows his consciousness of the great solemnity of nature. By 1910 Henneberg had apparently turned his artistic attention from photography to painting and relief printing.
